LOXLEY, Ala. (AP) - One person is dead and up to 20 injured after a charter tour bus carrying Texas high school band students home from a competition at Disney World plunged into a ravine near the Alabama-Florida line.

Baldwin County Sheriff Huey Hoss Mack confirmed the death Tuesday morning while talking to new reporters.

Baldwin County Sheriff's Office Major Anthony Lowery said the bus plunged off Interstate 10 into a deep ravine early Tuesday and multiple helicopters responded.

About 45 people were on board the crashed bus. The students were from Channelview High School east of Houston. A second bus of students from the high school pulled into the high school parking lot under police escort Tuesday afternoon.

Mack says all of the people on board were brought to 10 hospitals in Alabama and Florida.

The sheriff says the bus entered the median on Interstate 10 and then fell into the 50-foot ravine Tuesday at about 5:30 a.m. It wasn't immediately clear why. The interstate was closed down in both directions after the crash.
